1.1 This specification covers aluminum and aluminum-alloy
drawn tube and drawnpipe in straight lengths and tube in coils
for general purpose applications in the alloys (Note 2), and
tempers shown in Tables 1 and 2 Coiled tubes are generally
available only as round tubes with a wall thickness not
exceeding 0.083 in [2.00 mm] and only in non-heat-treatable
alloys
N OTE 1—For drawn seamless tubes, see Specifications B210 and
B210M , for tubes to be used in condensers and heat exchangers,
Specifications B234 and B234M , and for seamless pipe, Specification
B241/B241M For extruded structural tube and pipe, see Specification
B429
N OTE2—this specification use of the term alloy in the general sense
includes aluminum as well as aluminum alloy.
1.2 Alloy and temper designations are in accordance with
ANSI H35.1/H35.1(M) The equivalent Unified Number
Sys-tem alloy designations are those ofTable 3preceded by A9, for
example A91060 for aluminum 1060 in accordance with
Practice E527
1.3 For acceptance criteria for inclusion of new aluminum
and aluminum alloys in this specification, seeAnnex A2
1.4 The values stated in either inch-pound units or SI units
are to be regarded separately as standard Within the text, the
SI units are shown in brackets The values stated in each
system may not be exact equivalents; therefore, each system
shall be used independently of the other Combining values
from the two systems may result in nonconformance with the
standard
1.5 This standard does not purport to address all of the
safety concerns, if any, associated with its use It is the
responsibility of the user of this standard to establish
appro-priate safety and health practices and determine the
applica-bility of regulatory limitations prior to use.

inspection at one time
7 Chemical Composition
7.1 Limits—The material shall conform to the composition
limits specified inTable 3 Conformance shall be determined
by the producer by taking samples in accordance with E716

accordance withE607,E1251,E34or EN14242 At least one
sample shall be taken for each group of ingots poured
simultaneously from the same source of molten metal If the
producer has determined the composition during pouring of the
ingots, he shall not be required to sample and analyze the
finished product
N OTE 3—It is standard practice in the United States aluminum industry
to determine conformance to the composition limits prior to further
processing of ingots into wrought products Due to the continuous nature
of the process, it is not practical to keep a specific ingot analysis identified
with a specific quantity of finished material.
7.2 If it becomes necessary to analyze material for
confor-mance to chemical composition limits, the method used to
sample for the determination of chemical composition shall be
by agreement between the producer and the purchaser Analy-sis shall be performed in accordance withE716,E607,E1251, E34or EN 14242 (ICP method) The number of samples taken for determination of chemical composition shall be as follows: 7.2.1 When samples are taken from material each weighing
1 lb/linear ft [1.7 kg/linear m] or less, a sample shall be taken
to represent each 2000 lb [1000 kg] or fraction thereof of material in the lot
7.2.2 When samples are taken from material each weighing more than 1 lb/linear ft [1.7 kg/linear m], a sample shall be taken to represent each 6000 lb [3000 kg] or fraction thereof of material in the lot
7.3 Other methods of analysis or in the case of dispute may
be by agreement between the producer and the purchaser

ANNEXES
(Mandatory Information) A1 BASIS FOR INCLUSION OF PROPERTY LIMITS
A1.1 Mechanical property limits are established in accord
with Section 6, Standards Section, of the most current edition
of the Aluminum Standards and Data and the latest edition of
the Aluminum Association publication “Tempers for
Alumi-num and AlumiAlumi-num Alloy Products (Yellow and Tan Sheets).”
A1.1.1 Limits are based on a statistical evaluation of the
data indicating that at least 99 % of the population obtained
from all standard material meets the limit with 95 %
confi-dence For the products described, mechanical property limits
are based on the statistical analyses of at least 100 tests from at
least 5 cast lots of standard production material with no more
than 10 observations from a given heat treat or inspection lot
Mechanical properties limits for press solution heat treated
products have specific additional requirements which are
provided in the “Tempers for Aluminum and Aluminum Alloy
Products.”
A1.1.2 Limits denoted as “Tentative” by the Aluminum
Association may be included Requirements for tentative
property registrations are defined in the latest edition of the Aluminum Association publication “Tempers for Aluminum and Aluminum Alloy Products.” Tentative property limits are established at levels at which at least 99 % of the data conform
at a confidence level of 95 % Tentative property limits, which are subject to revision, shall be based on a statistical analysis of
at least 30 tests from at least 3 cast lots of standard production material with no more than 10 observations from a given heat treat or inspection lot Where tentative property limits are listed, they shall be shown in italics and footnoted as Tentative
in the standard
A1.1.3 All tests are performed in accordance with the appropriate ASTM test methods
A1.1.4 Mechanical property limits in this metric issue were derived from the inch-pound system limits that were developed under the above principles As test data on metric dimensioned specimens are accumulated, some refinement of limits, particu-larly for elongations measured in 5D, can be anticipated
